Soil engineering is the process of applying scientific and engineering principles to the design, construction, and maintenance of soil structures such as foundations, retaining walls, roadways, and airfields. Soil is a vital natural resource that is used for many different purposes such as agriculture, residential development, commercial development, and industrial development. Soil engineers are responsible for ensuring that the soil supports the weight of these structures and does not collapse or erode over time.

Soil engineering is the application of engineering principles to the design, construction, and maintenance of soils. It includes the development of soil criteria for projects, the selection and use of soil improvement materials, the design and installation of drainage systems, and the assessment of soil stability. Engineers who specialize in soil engineering are responsible for ensuring that our roads, bridges, and other infrastructure are built on stable ground that can support their weight. They also work on projects like dams and levees to make sure that these structures stay standing during floods. And by improving drainage systems, they help reduce the amount of flooding that occurs after heavy rains.
